MOUHANNAD KANTAR, M.D. appears in the CMS NPPES registry as a Geriatric Medicine (Family Medicine) Physician provider holding M.D. credentials at 1051 ESSINGTON RD STE 290, JOLIET, IL, 60435, with a listed phone of (815) 773-7827. NPI 1710127576 was issued on 03/05/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KANTAR most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 15,945 prescription claims written by this provider, covering 717 Medicare beneficiaries and totaling roughly $1.3 million in drug spend, split 11% brand-name and 89% generic by claim count, with an opioid prescribing rate of 2.6%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 36.1229/100 for the 2023 performance year (Quality 41.6667, Cost 43.4947), compared with the national average of 83.1.

Geriatric Medicine (Family Medicine) Physician is a narrow specialty nationwide, with 1,779 enrolled providers across 52 states and an average of 4,854 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
